초록/해제  
요약Many vertebrate species across the planet are experiencing major declines due to rapid expansion of urban areas, habitat destruction for animal agriculture, and human-caused climate change, among other drivers. Recently, the establishment of public data repositories for species occurrences and genetic sequence data have begun to resolve some of the former data limitations that inhibited conservation biologists from acting on declines due to lack of fundamental knowledge for many species. Conservation biologists are therefore primed to now make immense strides in addressing species declines by applying these publicly available datasets to species conservation worldwide. Here I describe two primary approaches to species conservation in the era of big publicly available data using genomic sequencing data and community science occurrence records. Specifically, in Chapter 1, I demonstrate how whole genome datasets can be used to evaluate the barrier effect of roadways on wildlife movement and gene flow in a North American ground bird, the California quail (Callipepla californica). I show that compared to other factors including differences in environment or habitat suitability, the presence of roads is the most important factor shaping quail gene flow in Southern California. In Chapter 2, which is now published in Journal of Heredity, we use PacBio HiFi long reads and Omni-C chromatin-proximity sequencing technology to generate one of the most complete de novo genome assemblies for an abundant and widespread North American bat species, the Yuma myotis bat (Myotis yumanensis). In Chapter 3, I leverage the novel genomic resource generated in Chapter 2 to summarize genome-wide diversity, historical demography, and range-wide phylogenetics of Yuma myotis to evaluate current subspecies designations and establish genomically-informed management units. Through this work, I found that genomic datasets are generally discordant with existing subspecies designations, revealing two primary genomic groups of Yuma myotis across North America. Additionally, I found that populations of Yuma myotis have high genome-wide diversity and high estimates of contemporary effective population sizes across most populations assessed, which presents a positive conservation outlook for the species. In Chapter 4, which is now published in PLOS ONE, we demonstrate how another big data source - community science data from iNaturalist - can be used to evaluate urban affinities of Southern California native vertebrate taxa. Taken as a whole, this body of work demonstrates how big data sets can be applied to conservation on multiple spatial scales - from guiding local biodiversity initiatives for the City of Los Angeles, to suggesting range-wide, continental-scale management units for species conservation.
